I love knee warmers. I put the gripper elastic over my shorts, and they stay in place perfectly. I've almost quit using leg warmers because knee warmers and long socks work just as well. If I'm wearing longish shorts, my regular crew-length smartwool socks almost touch the knee warmers. When I warm up, I can push the socks down and the knee warmers up and/or down. My arm warmers are fleece and are almost too hot much of the time. I made myself another pair of arm warmers by cutting the toes off a pair of longer socks.
